Status

1.

NNI requirements documents being developed in the IETF ccamp and ipo working groups in parallel with the ITU-T work on G.807/Y.1302, G.8080, and many other drafts.

Formal communications, Cross-pollination by company representatives

Ongoing collaboration by company representatives, IETF Design Team working to align routing requirements

2.

Parallel work by ITU-T on permanent virtual circuit based on NNI with work at IETF work on both switch service based on optical UNI and permanent virtual connections based on optical NNI

Ongoing collaboration by company representatives

3.

10GbE WAN PHY may not interoperate with interfaces developed using STM-64 specifications

Adaptation in draft revision of G.707

CLOSED

4.

IEEE 802.3 Ethernet in the First Mile Study Group addressing work that should utilise Q.2/15 work on physical layer portions of Passive Optical Networks

Communication Statement sent to IEEE 802.3, Q.2/15 selected liaison to help coordinate work

Under study in Q.2 & 4/15

5

Metropolitan optical networks being developed independent of established standard interfaces, assuming they are stand-alone networks

Metro optical networks description included in OTNT SWP

CLOSED

6

IaDI standardization has different concepts among the different questions. What is necessary? Is the difference in opinion simply based on different interpretations of the IaDI definition?

Draft G.696.1 (G.IaDI) under development in Q.16/15

CLOSED

7

OTN Routing and how to deal with physical impairments on logical routing decisions

No recent proposals, possible non-issue

Inactive

8

Optical Supervisory Channel (OSC) has slightly different definitions and views of standardization among the different questions. What is necessary?

Proposals considered by Q.12/15 and Q.16/15

Inactive

9

Ethernet (GbE, 10GbE) is supported as a client of the OTN, but is additional standardization required specific to Ethernet?

Liaisons to and from the MEF, continuing work by Q.9, 11, & 12/15 on Transport of Ethernet Frames

CLOSED

10

OTN and ASON Framework Recommendations have been proposed in discussions. G.871 is valid (but out of date) as a framework for OTN. The new Optical Transport Networks & Technology Standardization/Work Plan will provide frequently updated information. Are framework recommendations necessary?

Options considered in Q.19/15

Inactive

11

Optical transport network terminology is inconsistent across the industry and in some cases even across the ITU-T. What about using G.871 as the holder for normative definitions for OTN?

SDH, OTN, and ASON vocabulary Recommendations developed for consent

CLOSED

12

Characterisation of optical monitoring parameters, which would be required for all-optical networking, remain undefined. Which parameters should be used at an all-optical measurement point, how should they be measured, and how should they be used?

Draft G.697(G.optmon) prepared by Q.16/15 (for consent), identifies possible measurements

Network requirements in scope of other Questions

13

Multiple ITU-T SG15 questions have discussed the standardization of OTN GCC contents. Is coordination between the questions required?

NO, each group standardize the application within its scope

CLOSED

14

Optical control plane protocols to support ASON are currently being discussed, revised, or defined in several organizations, including ITU-T SG15, the IETF, the OIF, and the ATM Forum.

Formal communications, Cross-pollination by company representatives and liaisons

Ongoing collaboration by representatives and liaisons, IETF Design Team working to align routing requirements

15

GFP being considered for multiple applications not fully addressed by the current standardized version. Enhancements for different applications either need to be included in G.7041 or they will likely be captured in other application specific documents, resulting in multiple "versions" of GFP.

Q.2/15 used unique encapsulation for PON applications
